Flight Processor Virtualization for Size, Weight, and Power Reduction

A flight software system that was originally deployed on six separate physical processors is modeled using a single processor. Goddard Space Flight Center, Greenbelt, Maryland This work demonstrated the cost-saving and fault-tolerant benefits of virtualization technology by consolidating the flight software from multiple flight processors into a single virtualized system. In this study, a flight software system that was originally deployed on six separate physical processors was modeled using a single processor and a real-time embedded hypervisor.

Massively Parallel Dantzig-Wolfe Decomposition Applied to Traffic Flow Scheduling

Future decision support tools may make use of the model with commercial-off-the-shelf software and hardware. Ames Research Center, Moffett Field, California Traffic flow management (TFM) of the National Airspace System (NAS) endeavors to deliver flights from their origins to their destinations while minimizing delays and respecting all capacities. There are several models for solving this problem. Some models aggregate flights into flows and others consider controls for individual flights. Typically, the latter set of models is computationally difficult to solve for large-scale, high-fidelity scenarios. One of the more heavily studied aircraft-level models presented by Bertsimas and Stock-Patterson (BSP) has runtime concerns that should not be overlooked, but it neatly describes the issues associated with TFM (respecting capacities of airspace resources and the schedules of individual aircraft).

Mission Control Technologies (MCT)

Ames Research Center, Moffett Field, California MCT enables users to compose software from objects that can be assembled by end users to create integrated functionality. Applications are eliminated in favor of compositions of “live objects” that can be combined in different ways for different users and missions as required, in contrast to the more traditional software development method of pre-determining functionality and building a monolithic application.

Designing Reliable Robots for Moon Exploration

Simulation plays a key role in developing robots to explore the Moon. Astrobotic Technology, Inc., Pittsburgh, Pennsylvania Equipment for space exploration is almost impossible to test on Earth. Testing is expensive and cannot replicate the conditions of launch, cruise, landing, and travel across a planetary surface. As space exploration shifts to the private sector, Astrobotic Technology, Inc. is taking the lead in delivering affordable robotic technology. The company uses ANSYS technology to stay competitive, virtually testing its lunar robots on time and under budget.

Designing Smaller Magnets for the Large Hadron Collider

CERN designs a smaller and more powerful superconducting accelerator magnet using ANSYS multiphysics tools. FEAC Engineering, Ioannina, Greece The European Organization for Nuclear Research (CERN) requires new magnets that are smaller than their predecessors to accommodate new instrumentation. Because of their size, these magnets need to generate a 24 percent stronger magnetic field and the structure must provide for near-zero deformation of the conductor. Even a small deformation could increase the electrical resistance and raise the temperature enough to cause the conductor to lose its superconducting state. Engineers addressed this challenge using ANSYS electromagnetic, thermal, and structural simulation tools. Coupling the multiphysics domains in the ANSYS® Workbench® environment allowed the team to optimize the design by simultaneously considering all of the physics.

Composite Sports Car Body Design

KTM Technologies quickly and reliably designs a composite sports car using ANSYS technology. KTM Technologies GmbH, Salzburg, Austria The use of composites is rapidly growing across many industries, fostering the need for new design, analysis, and optimization technologies. Every industry feels increasing pressure to launch breakthrough products that outperform competitors and meet market needs. For many design applications that require strong, yet lightweight materials, layered composites are ideal. Even so, faster, more frequent product introductions and new technologies cannot compromise ultimate product quality, reliability, and speed to market.
